I noticed that my automatic garage door kept popping open after
closing- then i noticed that one of the cables was off the drum. the
main spring is fine and i got the door in the down position with the
cables attached to the drums- there is still some slack. how do i fix
the cables and drums so i can operate the door without the cables
coming off the drum.
The attachment of the main spring(s) to the drum shaft has to be
loosened, the spring end(s) rotated, and then retightened.
Unless you are very handy, very careful, and very gutsy, most folks on
this newsgroup, including me, will emphatically warn you NOT to do this
But, if you insist, at least go here and study, study, study before you
